Anyone know the trick to opening a Kitchen Mama can opener?

[Special Stick For Kids]

The battery contact spring corroded on mine. Once you open it up the same way as the OP, i cleaned it with a fiberglass pen and it was good as new. No need to go past the battery cover though since the contact spring is accessible from outside the can opener.

Awful battery contact issue, these gadgets are thrown out every time the $0.10 spring corrodes.

Same issue, thought mine was dead because of the battery but it was just that.
